Recently I had a chance to ask Greene about wormholes (a hole which some scientists think might exist, connecting parts of space and time that are not usually connected), time travel and other mysteries of the universe. I asked him a milliondollar question: What if I went through a wormhole and prevented my parents from meeting? Most of us believe that the universe makes sense, Greene said. Although there are several interesting theories about time travel, he added, the laws of physics would probably prevent something so illogical from taking place. The good news is that the time paradox (悖論) is open for future physicists to solve.（英語(yǔ)）高中英語(yǔ)閱讀理解(教育文化)技巧(很有用)及練習(xí)題一、高中英語(yǔ)閱讀理解教育文化類1．閱讀理解 Brian Greene, a professor of physics and mathematics at Columbia University, has created an online science education platform. He tries to build a bridge with things you know about, and then bring you across that bridge to the strange place of modern physics. When asked how physics could bee more exciting for kids, Greene said that books by Stephen Weinberg, Leonard Susskind, and other physicists, make it a great time for people who want to learn about big ideas but aren39。 When I pointed out that some students still might find physics boring, Greene said that the key is to teach them about things that are strange. The basic stuff is important, Greene said. But I think it39。 Greene has followed Albert Einstein39。s about experimenting, showing an interest in strange phenomena (現(xiàn)象)—and having fun!（1）A milliondollar question is probably very . （2）The books by Weinberg and Susskind . boring to read mainly about maths popular science books only popular among kids（3）According to Paragraph 4,which of the following does Greene agree with? physics is a boring subject. plays an important role in studying. is not necessary to learn all about physics. is easy to describe black holes and the Big Bang.（4）In the last paragraph, Greene hopes that . can love science and physics can do well in physics exams can have fun with experiments can find more strange things in life【答案】 （1）B（2）C（3）B（4）A 【解析】【分析】本文是一篇說明文，物理和數(shù)學(xué)教授Brian Greene希望更多的孩子可以對(duì)現(xiàn)代物理學(xué)感興趣。根據(jù)第二段Greene對(duì)這個(gè)問題的解釋以及他說需要未來的物理學(xué)家去解決可知,作者提出的這個(gè)問題非常難。 （2）考查推理判斷。t yet ready, perhaps, to learn maths39。故選C。根據(jù)第四段可知,當(dāng)作者指出一些學(xué)生覺得物理無(wú)聊時(shí),Greene說重要的是向孩子們講述一些稀奇古怪的事,并描述一些諸如黑洞和宇宙大爆炸的現(xiàn)代物理現(xiàn)象,如果孩子們知道了這些,他們中的一些就愿意了解所有詳細(xì)的內(nèi)容。故選B。根據(jù)最后一段中的“Greene has followed Albert Einstein39。故選A。2．閱讀理解 recreational(消遣的) screen time to less than two hours a day, along with enough sleep and physical activity, is associated with improved cognition(認(rèn)知), according to a study published in The Lancet Child amp。The study included about 4,500 US children aged 8 to 11 and measured their habits against the Canadian 24Hour Movement Guidelines for Children and Youth.
